I've been diving a single 15 bp&w for a while. I'm looking into what makes a good twinset whilst I save my pennies to pay for one. 2*12ltr 232 euro round bottoms, 2* Apeks DS4 's with ATX50 & ATX40 secondaries, Evolve 40lb wing. Well trodden path, seems to be the way to go. But which manifold? I was leaning towards the Halcyon one, but then had a chat with a bloke about the Apeks manifold. Ok, he was trying to sell it to me but it did look like a well put together bit of kit. Nicely built and very smooth valve operation. Any thoughts?
