Weight Tubes

[Kamu]

All I'm always tinkering around with my setup. So I'm thinking about using weight tubes to get  more overall arrow weight. My concern is getting my arrows so heavy that I start taking away from performance. My current setup is a Acadain Tree Stick and I'm pulling around 44 pds at 26 1/2 inch draw length. My arrows are Gold tip trad's 3555 weighting right at 450 grains. Thinking of jumping them up between 580-650 grains. Any thoughts would be great!

I would consider replacing the aluminum inserts with 50gr. brass inserts, for 500gr. total weight or 100gr. brass inserts, for 550gr. total weight. That will also put the weight up front where it will do the most good.
Or, shoot a heavier field point and/or broadhead.
Gonna have to re-tune. But then again, you said you like to tinker.lol

I tried weight tubes,they will bring the weight of your arrow up.But I don't use then anymore,the biggest downfall is they will pop the nock out if you hit a hard object like when stump shooting and sometimes with a hard target.I just didn't want to glue the nocks in to keep them from popping out.I prefer to use heavier inserts and maybe a heavier spine arrow and retune to get my arrow weight up.

I don't like weight-tubes also. I tried everything to put into the shaft, but no succes.  

I use GT shafts as well and these days I do the following: I buy some small screws which fit into the nock and eventually the shaft. Adding weight to the nock means adding weight to the front in order to keep your dynamic spine the same (adding weight to the nock means a stiffer spine). The screws I use in my current set-up fit perfevtly in the nock and weigh 20 grains. So I increased my front-weight with 20 grains. A profit of 40 grains. Using longer and/or heavier screws means more profit ofcourse.
I glue the screws into the nock with construction-glue. This glue swollows a bit. I let the nocks cure for 24 hours. After curing I remove some glue which eventually pops out the nocks. The screws stay rock-solid in.
A side effect is, that the glued-in screws protects your shaft when shooting a Robin Hood!

Hope this helps

I didn't care for weight tubes when I tried them; they popped my nocks out and made my arrows spin terribly.  I'd bump insert and point weight.

Just glue the nocks in.  No more problems with weight tubes.

Increasing point or tip weight will require you to retune.  50 grains can put you with a completely different arrow shaft.

Weight tubes will change your tune, but much less so than point weight.  You may be able to add 100 grains of weight tube before you have to change shafts.
