    Carbon wheel opinions -- 27.5, 30mm BTLOS vs Light Bicycle

    I'm looking for some opinions (dangerous, I know).

    Bike - Ibis Mojo HD4 (160mm/153mm travel)
    Tires - Probably 2.3-2.5" Minion DHF front or similar and 2.35-2.6" Aggressor or Riddler or Rock Razor or similar rear.
    Rider weight - 130 lbs
    Use - mixed use, some 3-5k climb days, some lift-access days, routine riding is mostly smooth terrain with occasional jumps or chunks. I've historically been easy on wheels (no tacos, occasional wobbles)

    I already have the Ibis 738 (38mm internal width) alloy wheelset that I plan to keep as backup/changeup wheelset

    I'd like to buy a daily driver wheelset that's lighter but can still party and can still accommodate 2.6" tires as I'm not sure where I'm going to land on ideal tire sizes. I'm thinking 30mm is my sweet spot.

    I'm cross shopping BTLOS and Light Bicycle. DT350 hubs, 28h, straight pull, centerlock, brass nipples. The BTLOS come with D-light spokes and the LB have DT Swiss Competition. These are the basic configurations I'm looking at:

    LB AM730 (asymmetric) $855 shipped w/ a discount code
    LB 650bc05 (non-asymm) $640 shipped w/ discount
    BTLOS standard (asymm) $811 shipped
    BTLOS premium (asymm) $881 shipped

    I'd love input on the following:
    1) Internal rim width, does 30mm seem like a good plan?
    2) D-light vs. DT Swiss Comp -- D-lights seem better, right? But how much does that matter?
    3) Assym vs. non-assym rim profile for the LB rims. The non-assym are less expensive and lighter. How much is the strength trade off?
    4) BTLOS vs LB -- any strong opinions on either one?

    If you're still reading, thank you, and sorry for the length of the post.

    1. 30mm is good for that width range.
    2. At your weight, D-light would be fine and be lighter.
    3. These rims are already super stiff laterally. Get non-asym if it's cheaper.
    4. Whichever is cheaper.

    At your weight and your history on wheels I feel you would be fine on either option.

    I would also throw carbonfan in as well.

    If your budget can be stretched check out the guys from BC - we are one - my next set of rims will be from there as long as they keep producing the stuff locally.

    Thanks for the replies. I'll check out Carbonfan and We Are One. I think I'm leaning toward the symmetric LBs.

    Last month I bought a pair of i29 with 240 hubs and D-Light hubs for my Ripley from BTLOS. Been pretty happy with them so far. Good quality build and they (vendor) are easy to work with. They even sent some spare spokes and nipples. Packaging for shipment was top notch.
