it did helpThe 150 spring should give you around 460-500 fps (depending on other factors), which should be high enough to use .36's with. I would stay away from the 190 because unless you have upgraded the sears and not just the housing, the trigger would most likely break. Although the 150 spring would be strong enough, im not sure you absolutely need it. Form what i've heard, the utg kit comes with a spring that is actually very similar to an m170. Laylax is a good company that you will probably want to get in the end, but if an m170 is what you want, I wouldn't compromise for something you don't want (150 or 190).
You could also try looking on other websites such as airsoft atlanta, airsplat, or LA wings inc. if you take a look you might find what your looking for, for a more reasonable price than on red wolf.
Hope this helped
I was able to find a 170 spring on another website, but it is way more expensive then on airsoft gi. So will the utg upgrade kit suffice for .36g bbs? I have a lack of money in my paypal and would like to have money left over.
Also, I didn't exactly buy the utg upgrade kit. I bought a similar one off airsplat that is for the same l96 but a bit cheaper.

It is essentially the same thing ( I think ) as the picture is almost exactly the same except it looks like an employee went on microsoft paint and simply pushed the image around a bit.
