First: don't double-post.
Second: it depends. What are you looking for? There's really no "bad" mag... some people go for pure-power mags, but not me. Heh. I have only 3 mags at level 200 right now:
My RAmar's, a Pushan - 55/65/35/45
My HUmar's, a Rati - All 50
My FOnewm's, a Nidra - 60/60/50/30
I dunno what I want to do with my HUnewearl's just yet. All I've planned so far are the PB's... Farlla, Golla, Estlla. I usually decide their final stats after they hit level 30 or so (which means, after they've hit their rare form).
I do have this plan, to create several alternate mags for different purposes... I'm gonna start raising a pure-power mag for my RAmar soon. You could always two of them side-by-side for different purposes (I'm assuming since you have a character above 100, that you have plenty of money to give your HUnewearl for food).
