So I pretty much rode a Bataleon The Jam all season last year, good board, decided to try something different this season and something that could handle All-Mountain/Powder better and decided to go with the Never Summer SL-R.
As far as my riding style, I like riding powder and steeps, dont do too many jumps/park features but Ill hit the occasional natural feature...
The TBT feature is nice, edge to edge is a lot faster than a standard cambered board, the board is definitely fast going flat based. The board felt like a regular cambered board on powder though, you're still fighting the camber to stay a flot and have to lean back quite a bit. TBT is definitely not "edge catch" free, its definitely more forgiving but you can still catch your edges.
Rode my SL-R on 2 powder days here in the PNW, did plenty of groomers and powder runs. I have to say I really love this board, its just really easy and playful to right you can throw the board around and do whatever you want with it. Powder runs were definitely easier, still have a bit of back leg burn but I think thats just due to being early season only having gone 2 times. Edge hold is amazing, I found times where I thought I would wash out but the SL-R just kept you locked into the turn. Going over choppy/bumpy terrain was a total breeze it went over anything/everything I threw at it and the dampening on the board is great. In my 2 days with the board I have only caught one edge due to it being myself, other than that this board is very forgiving, there were a lot of times I thought I was going to eat it but the board just rode it out.
Overall I definitely like the SLR more for my type of riding, its just an more fun board overall and very easy to get used to and have fun in the deep powder
