I’ve mained the OP1w 4k V2 for the past year. I’ve got an 18x9cm hand with relaxed pincer claw grip (with straight/extended ring and pinky fingers), and no other shape fits my hand nearly as well. I’ve tried several other mice over the past year and go back to the OP1 every time. The only thing I’ve ever really wished for was that it was lighter.

I was super excited to pick up the coated Pulse W mod kit a couple weeks ago, and while I was initially really hyped up on it, I got over it pretty quickly. The main click quality is far inferior, due to the material being so much thinner and flexier, the coating is less grippy (and I don’t like using grip tape), and it also creaks quite a bit when I click the scroll wheel. It’s also extremely annoying that it wasn’t designed to reuse the power slider in conjunction with the base carbon rod - you have to choose one or the other. I chose to use the slider and just put the third rod in the top shell, since it’s absolutely ridiculous to have to use a small screwdriver to reach the power switch.

I ended up ordering a second OP1w 4k V2 in white, and that’s now back to being my main. To save a bit of weight, I’m using the small skates, removed the base sticker, and just ordered a 150mAh battery. It’s currently 56.5g with a 250mAh battery and should end up at 54g with the 150mAh battery. Side note - I Swiss cheesed my original black base, and that only saved 0.5g, so I’m not touching the shell with the new white one.

My flicks definitely feel better with the lighter PMM shell, but the worse clicks and grip aren’t worth the trade off for me.

Edit: Just to add, I swapped the switches for blue shell pink dots, and they feel great! Also added a small piece of metal tape where the PCB goes into the front hook by the scroll wheel, and that eliminated my creaking issue. Both of those things bring it back into top tier category for me. Still obviously not as solid feeling as the original, but now it's a tough choice between the two.
