" I have had some several hit and miss attempts when I have rung this (often ending with me being shouted at!). my main issues are not being to count my place (something I have already struggled with anyway) "
Several points here. The first on is your struggle to count your places. You say you can ring Plain bob and grandsire ok - is this on the treble or inside? If on the treble, it's quite easy to plain hunt over all the bells slowly, then do the same quickly and lead, without really counting which place you are in. You will certainly need to be able to count which place you are in if you are ringing inside. Do you know why you are struggling with this? Are you thinking of the number of the bell you are following or trying to memorise the order? It's difficult to remember 2 numbers at once, so try not to think of the number of the bell you are following. If my learners are struggling to count where they are, I get them to count out loud. If they then find it hard to see which bell to follow, I will point it out, but NOT say the number as this can make them lose count. Also, don't count which place you are in too soon, as this can lead you to count the next place too early. Count as your bell strikes ie nearly at the ends of the pull, or if you do count as soon as you pull off, then make it slow - ie seconds said really slowly so it lasts until almost the start of the next pull (this is hard to explain). Practice counting when standing behind someone. or on your own going up and down stairs.
The advice Rosaling gives above is good, about ringing the treble to plain minor first to help with ropesight. Watch people's arms and try to find the one whose arms are closest to matching where yours are. I don't watch ropes- I watch the position of hands and arms.
Someone also said about treble bob on 4- this is also good. I would also start by doing Treble Bob Hunt on 4 and then 6 as the bells come in the same order as plain hunt which will help with the ropesight.
If you have not rung Plain Bob inside yet, you will also need to work out how the dodges work. A dodge is a change of direction for ONE BLOW ONLY. So in teble bob, ignore for a moment the dodge on the front as that starts half way through the dodges. So you plain hunt to 4ths place, which is at handstroke, so the dodge is a quick blow at backstroke. If you can't see who to ring after, just ring a bit quicker for ONE blow. This is your 3/4 UP dodge - because you are going UP to the back. Then hold up for 3 blows -4ths, 5ths 6ths -another handstroke. You can now dodge 5/6 UP, so another quick blow for 1 backstroke. If we are treble bobbing on 6, then you do your 2 blows in 6th place before starting you DOWN dodges. So it's a quick blow at hand, before holding UP and back for the dodge into 6ths place. Now you can start to hunt down to 3/4. So it's quickly to 5ths, 4ths and 3rds - which is the handstroke. Then hold up to take a step back to 4ths. Try and think of the dodge as ONE blow only as a change of direction on the backstroke. Good bell control is vital - you cannot move the bell about frequently without it, so it can be useful to ring on your own with someone else counting the places, and you change direction when needed. So you ring slowly as they count 2nds, 3rds, 4ths then as they count 3rds you ring quicker. Or you can count out loud as well. No ropesite needed!
Finally, about being shouted at. This is difficult, because it is sometimes hard to correct someone without raising your voice. It needs to be done quickly or the touch will disintegrate (it's easy in TB to go the wrong way or get at the wrong stroke), so can often sound abrupt which is not usually the intention. They often need to speak loudly to be heard -especially if you are looking the wrong way, as is sometimes the case. It is best to have someone behind you to correct as needed and make sure they tell all the ringers to try to keep quiet if you go wrong and leave it to the stander. Unless they are abusive it is not usually done with malice, especially if they know you are learning. I have hardly ever (can't really remember an occasion) when a learner is shouted at maliciously, though it can happen. It's usually reserved for an experienced ringer who should know better.
