Thanks for the replies!  I'm evaluating the value of the "internal frame".  The options seem to be: the Nimbus Great Northern & Ostrom's "Algonquin" & "Wabakimi".  IF I decide to go with internal frame, those are my choices.  Having said that, I'm not altogether keen on the notion of GG's Chinese labor & possible use of 12 year-old's doing the sewing.

On the other hand, putting aside internal frame offerings, the top-of-the-line options seem to be Ostrom's WiniskIII and CCS's Guide Pack.  I'm in the process of evaluating the difference in value between the two.

Ostrom's stuff IS expensive.  Maybe it's worth it.  I'm trying to sort that out.  I've sent an e-mail to Dan Cooke asking him to elaborate on materials, etc..  I have absolutely NO question re: his workmanship on CCS products (I already own a canoe spray skirt AND a screened-in lean-to shelter & they are great!).  Ostrom packs his website info with tons of material info.  Dan offers less info on his website so I'm asking for more.  IF materials are equal or close, I'll go with the CCS product since I am quite comfortable with workmanship.

Unless, of course, I decide the value of the internal frame overshadows other considerations.  In that case, it seems to be a Nimbus Great Northern versus Wabakimi (Ostrom offering) choice.

Thanks, again, for the inputs.  I'll keep you posted re: my choice.
