Simms G3 Wading Boots?

I've finally killed my second pair of LL Bean River Treads Aquastealth
Studded boots while tramping around on the Colorado this past week
(soles are peeling off). Although I've loved these boots, this is the
second pair that has failed me over the past 5 years (god bless LL
Bean and their guarantee). I've also found them to be relatively stiff
and heavy for long hikes.

I'm looking at the new Simms G3 Felt Studded wading boots. Was
wondering if anyone out there has used these boots, and if so what was
their experience with them. I'm a bit concerned about the durability
of the felt soles over some of the terrain I travel to get to my
fishing holes - but I imagine the studs will make them a bit more
sturdy.

Any help or insight would be greatly appreciated. Unfortunately due to
the fact that I'm returning my old boots for an exchange, I'm limited
by LL Bean's offerings - and other then their own boots they only
offer the G3 and the Simms L2.

Thanks in advance for any assistance.
