kg, kudos on the light arrow man. Question though, how is the flight? That seems on the line between needing a 400 rather than a 500. Different bows like or dislike more spine. I know my 101 seems to like a little stiffer shaft. To your original question though, how much speed did you lose?

about 20fps. if you use a light tip like a 75grain you will stiffen up the spine a heavyer one will weaken it. the flight is awsome 1"groups at 60 yds.

Unless I'm missing something even a GT UL500 cannot get down to 275grs finished.....the reason I'm asking is even at 55# 306fps at 29" 5grs/lb of draw sounds slow.
GT UL500 = 6.3grs / inch X 29 = 182.7grs
Tip = 80grs
Factory .246 nock = 10.4grs
Factory .246 insert = 14.6grs
Finished arrowbefore fletching = 287.7
Example three 2" Blazer vanes weighs 15grs itself, so even with feathers your finished arrow would be mid 290's and with even small vanes like Blazers around 302ish grains.
What did you fletch them with and did you actually weigh them or were you TOLD they weigh 275grs?

That's nice, your arrow has enough momentum at 60 yds to split a few hairs
