For abs hunters:
Get a dark barbed flail(or bronze scourge) to suppliment your big basher weapon. These are multihit, and as long as you stick to fauna you don't need the offensive bonus pracs give you, so no need to prac flails. The hunter bonus damage against fauna helps you here.
For abs warriors:
If i exp abs warriors i get 1 survival, 3 ride and 99 attack as fast as possible, then kill everything i can berserk. Then work on the weapon prac. Your big bashing weapon could be supplimented by a fencing or short blade to make use of the attack in brave mode, or a lance with charge pracced is also a common suppliment.
about bashing during exp:
I find mostly that bashing during exp isnt worth it untill higher level if at all. Also keep in mind that bash isnt really consistant untill level 30 either. The reason is that you loose rounds you could have hit for damage. If you have a club with relatively low ob going up against horned lizards or preds solo, then you kind of have to bash. I will still recommend a high ob weapon for these creatures and not bash.
Note that these are my opinions, but also my preferred methods.
As to where, exp are everywhere these days.
