I appreciate the replies. I feel like I should delete the thread since I gained the knowledge I asked, but I will keep it open in case anybody else ever has the same scenario. Thank you to all who helped answer my questions.
I have a Geurilla Gravity Gnarvana coming that I was fit for. I like my Hardrock and I still plan to upgrade it and use it to learn to work on instead of my Gnarvana. When I need to upgrade the fork on the Gnarvana, I will have similar knowledge I gained from working on my Hardrock.
For example tonight while changing the rotors, one of my bolts was stuck. I have learned to not strip the bolt; if you do, cut it with a dremel to make an opening for a flathead screwdriver and use that to turn the bolt out. I would rather learn that on a $250 bike than a $7,200 bike.
Last week I learned to bleed mineral brake lines. This week I learned when going up a size in rotors you need an adapter and next week I'll learn to add a new line to sram guide rsc brakes I purchased for my Hardrock.
After I choose a fork, I will gain that knowledge. I appreciate everybody sharing their knowledge and time with me, for free. Thank you.
