In reply to French Erick:
[Caveat: I may also be missing the point or misunderstanding you!]
If you're more suited to open-handing than crimping, then I (and loads of others?) envy you. When you go the other way, i.e. from crimping to open-handing - principally to avoid injury - it feels as though your open-hand strength is only about 40% of your crimp strength. Most depressing! If you stick at it, it seems as though open-hand strength comes up to about 85% of crimp strength. (Just my intuition; would be good to test it scientifically). And that's good - but God, it's an effort getting there. If you're already there, well OK, I accept there's the odd route where crimping is essential at the grade but why not just forget such routes and carry on open-handing?
Re holds, when I lived in Sheffield, I used to train on a 45% board with loads of wooden holds. I could get into position, crimp and pull on, say, a first knuckle hold, then go to a slightly smaller one nearby (keeping much the same body position), then go to an even smaller one (carefully, in time). I found this progression really helped. I'd end up using holds I'd never have contemplated in the beginning. And it translated very well to crimpy Peak limestone.
Maybe have a think about open-handing and progression with a wide range of small wooden holds? Just some thoughts...
