    Anyone use a carbon fiber backplate when diving double 104s? I've always dove with a steel backplate as that's all I've owned in the past, but I suspect that's overkill so I'd like to try something lighter. Seems like it should be fine in a drysuit with a set of 4th element arctics but figured I'd ask anyways.

    CF BP is a good choice, you don't NEED CF, but its benefits are reducing travel weight, and if you need more weight, you can choose where to put it (high/low/ditchable or fixed).

    Just make sure if you need a short plate, you use a short plate... that's more important than weight placement flexibility.

    The CF is plenty durable for heavy dubs and tsa abuse. But, I don't know if I would jam it under the tire of a vehicle stuck in mud like I "might" have done with a metal BP. ;-)

    thanks all. this is very helpful. i've never used trim weight when diving 104s with a steel plate, but i do use 4 pounds with a set of lp85s and 8 pounds when diving al80s. do ppl typically use trim weight with 104s and alum or cf backplates?

    I did not need any weights with the 104s and my Kydex backplate (which is practically the same weight as AL/CF). This was with a TLS350 and XM450 undies during C1 with @mer

    I have a DSS Kydex plate and have dove it with LP 108s before, no issues with the plate bearing the weight.

    Did you empty your tanks and make sure?

    Yep, emptied them down to just under 500psi on our day 0 shakedown dive at Troy. We got close to that on day 1 at Blue Grotto as well and confirmed it worked.
