I can't speak on DP. I have not used their gear but as I've said before about Geneza, I first used them in 2009 when they came out. Around 2010, I started using mostly only GP gear. I've always had consistent experiences with their products. I trust them, so much so, that I've used them for contest prep, which requires a lot of trust. If you start Halo at 3 wks out and find out it isn't working, you're not going to have a lot of time to make new plans. Speaking of halo, GP halo is the best I've used.
