I have skied 186 BGs for 4 years. 5 days on 189 108 Wrens this year (softer fiberglass, not really sure if it matters much).
If you plan to keep Rens and only want to buy one additional ski, Wren108. Or Woodman108. The Wren skis soft snow very well. I'd say as well or better than 193 EHPs, while being a lot more fun in other conditions. They are however not the ultimate crud/soft bump ski. There is a lot of tip rocker, and they climb over more than slice through.
If you buy two skis. BGs and one of the 96 wren/woodmans.
Obviously a lot of good skis outside of the on3p-bubble. Maybe 107 MSRs?
