Speaking for my game, I always like the training, and training scrolls aspect of old school RQ and have incorporated them into my game.
During down time I allow my players to train a stat in a way that is appropriate (Strength and/ or DEX training for gladiators, INT training in a library for Mage/scholars/nerds, CHA training for Lords and ladies, CON training from hunters, monks, etc). At the end of the training a Stat x 5 roll is made. If the roll is greater than the amount, I allow 1d4+1 IR towards the Stats improvement. Under, 1IR. Critical- 6 IRs. Fumble: -1d4 IRs.
In this way stats can be improved faster and PCs feel like they aren't quite so stuck with the lot they've rolled Stat wise.
Just a simple solution I've come up with that works for our group. They were getting antsy and liked the old training rules more, so I went for an amicable, simple middle ground.
