125-200cc ecj needle

Hi all. I've got a completely standard 2013 wr125 except for a PWK38AS fitted. The carb came delivered with a DDJ needle which I found (after trying DDL & DDK) gave the best response in the bottom half of throttle range but was a little weak above half throttle. If I raised the needle any further the bottom half was slightly rich but the response from 1/2 throttle was good.
I'm now running an ECJ needle (main difference to DDJ is a richer taper). This needle seems to me to give good response right through the range. I've even now set the powervalve back to the factory setting and didn't seem to experience the dreaded bog. Admittedly this was only on a quick test ride around the block.
For the record I'm running a 40 pilot, a/s 1.75 turns out and 180 main. A plug chop shows the main is one size rich but I prefer the piece of mind over the 178.
I'm just wondering if anyone else has tried this needle and how they felt it performed.
