the only vipers i see on cabelas website is the SS and the "ultimate SS" the ss is 259 and the ultimate is 339 or something.

i know the SS is alumanum and a nice stand. i own and use one. not overly heavy, comfy, packs easy, comfy, and did i mention comfy? i really like mine. i like the from bar. makes me feel secure and gives me somewhere handy to lay my bow with a nocked arrow. naps? no problem. i feel safe and secure and am comfy when i need to catch a few Zs. i like mine.

the ultimate seems to be the SS with a couple accessories. probably cheaper to buy it than the stand and the accessories...but the only accessories i put on mine was the front storage bag. i like it to keep my binocs, drink, stand accessories(like pull up rope, tie off rope etc it..) i like the drink and binocs and calls and such in it so its handy and i dont have to move to get them as i would if they were in a backpack or something...

i have 2 lock ons dad told me i need to use this year...i want to use them. make it nice to sneak in and out of stands i hunt a couple times a year and that...but man...wont be comfy at all, wont feel as safe without the bars around me, nowhere to rest the bow, no pouch to store stuff...yep...thats the stand i will kill deer from...they will be in the best spots and will be easy to sneak into and i will be alert...but i love my summit....i could use a nap in one right now! lol...
