I thought my 30-yard robinhood was good. Nice shot. Kinda bittersweet because now we're down 2 arrows and almost $20 lol.
Simple answer so it's easy for you to fix. Most new bows string and cable will stretch which will make your bow out of tune and or time. So after shooting for awhile take it in to your shop and have it re-adjusted. Second get rid of the flippin tube. Everyone wants a fast and quite bow but they keep adding more crap to them. those tubes are really loud especially when they are cold besides the slap in the face factor they can have. All just my opionion but it's what I would do before moving everything around on your bow and then having to do it again after you have it re tunned or timed.
Marking your peep is a great idea. One that is better is to have the peep SERVED in.. On my peep, the serving starts ABOVE the peep, then travels down TO the peep, then THRU the hole in the peep, and then BELOW the peep. It is ONE SOLID STRING, so it will not slide... Just a thought............
