In reply to The Ice Doctor:
> 1) Are there any routes up to the 5+ category that do not involve a series of abseils?
absolutely masses, if you are climbing routes at D/ED1,2 plus, then you will almost certainly be walking off back down PD routes.
The only routes where abseiling is technically essential (unless you plan to down climb V,VI etc.) are rock pinnacles, towers and the like, but you don't get much ice at the equiv of grade V going up those anyway.
But, as your asking this question, I imagine you haven't been? And perhaps sticking to PD/ easy AD for your first shot in the Alps will give you the chance of a second.
!! before anyone leaps in with some specific examples and flames me, I've slightly generalised, but it kind of fits with the OPs very general question.
