I solo pretty much exclusively, and I'm thinking about TRing (my first TR!) my Wiz18/Rog2 into an Artificer - this should make good use of my Mabar +5 Int tome.

What I'm wondering is, as I get on into late Heroic and then Epic levels, am I going to be eating a lot of damage without Evasion and a high Reflex save? My main character at the moment is a level 23 Monk, and I suspect that Evasion plus Spell Resistance and a Monk's immunities are shielding me from a lot of nasty stuff.

If I do splash, the question will then be Monk or Rogue - Rogue gets a nice pile of skill points and some sneak attack (which apparently works well with Repeaters?), Monk has a couple of bonus feats and a stance.

Are the capstone enhancements (items at character level or +1 enhancement to weapons plus weapon becomes implement) good enough to make Evasion too costly?

(Any other build advice would also be much appreciated - particularly with an eye to soloing!)
