Can I ask what type of sleights people are wanting to achieve by going to such lengths
Are you wanting to perform advanced sleights to magicians or do basic stuff for Joe Public ??
I perform 2 or 3 days a week to Joe Public and I've said before with card sleights, you don't have to do the mind bending stuff to bamboozle them. Its performance that counts, not an amasing dexterity.
With coins I do very little, I do Hopping Halfs that needs next to no skill and I do an effect of my own involving a coin switch. I don't think that I am a good coin merchant but a simple switch using the palm and the thumb palm (or clip) work more than enough for Joe Public to ever grasp I've cheated.
I'm 6' 2" and have hands the same size as my wife who is 5' 3" (No she doesn't have giant hands). I can palm and thumb palm everything except the little ones, 1p, 5p and 20p and I can manage on that because I know my limits.
I have said this before, you do not need to be a rocket scientist to perform. Spending your practice time at being a good performer is more important than learning a fancy coin or card sleight.
I love close-up, perform it all the time, but I don't go for the mega whiz stuff. But what I do perform, I do it well. Even when I've been out all night in the pub, or pubs, and that is what is important, performing well.
I've just been asked to do a magic show as a starter in a rock pub before the acts come on
I'm giving serious thought to this as it might damage my reputation

If I give it more thought and contemplate it, I'll seek advice on what everyone thinks I should go for
I'd be the starter in a dingy dismal and dark room, and that has its advantages

On stage, before 6 rock groups come on

Now how does a 50yr old cope with that
