Im an Elder Fencer So I know what you goin through. Depends on how good your other skills are and the equip. you are using really.
Personally for training I dont like bein bored and have just one account and computer...so for me Golems have always been out the question. If your like me and not a Golem Lover then:
weaker chars-
Black Solen Infiltrators- (while your at it you can stock up on zoogi fungus to do the solen ant quest for T powder and BOS. They are useful during events and you dont have to bank stuff. 3 BOS bags and 140 Tpowder = 4hrs or more of action with no banking required) Also good for training pets like Firesteeds, Mares, or other tamables that arent strong enough to take down Ogre Lords with ease 1 vs 1. The infiltrators are 80ish in wrestling like the trogs
midway chars-
Trogs- these r great because of the faster spwan rate...dont hit veryhard...are 80ish in wrestling...and as long as you dont go in with uber duber def chance increase you can get good parry gains also.
Cyclopean Warriors/Titans in Despise- Put here instead of weaker char cuz usually newer players dont have good magic def armor which Titans may cause trouble with but...if you got decent magic resists 55+ or so then it good choice. you get chance at arty drop. Decent place for low end pets too. Tone down the def chance increase and u can gain a lil parry....Trogs R better IMHO though...
Strong Chars-
Despise Ogre Lords- I say despise Ogre Lord because the artic ones dont have as good wrestling. Despise OL are around 90ish while the artic one are around 80ish. Also you get arty drop chance here without having to mess with any "real" high end monsters. If it gets boring jus carry a piece of black rock...black rock makes everything funs

good parry gains here too as long as you lay off the def chance increase.
Can also get Glorious Lord title on them which you can use to gain in sacrifice for self resurrections!
