Hello all,
I have been looking at bloop tubes for some time now and am thinking about getting a CC one (for cost reasons) and wanted to know what you thought about them. Also, does the length effect the accuracy at all, or do they effect it no matter the length? Thank you so much!

Putting any amount of weight on a barrel will influence the harmonics and thus performance. Sometimes it is an improvement and other instances it is a detriment.
Length will impact the clarity of your sight picture with iron sights and each person's vision is unique. Too long of an extension tube is not always better.

Bloop tubes are meant to lengthen your sight radius, and longer is always better.
The relative focus of front sight and target focus is based on their relative distance from your eye, and it is an inverse relationship, so even a few inches on the front sight can make a noticible difference. 6" or 8" can reduce the lens you need by as much as 0.25 diopters.

I like extension tubes. When I first got one my scores rose (then levelled off), I'm long sighted so having the foresight further away from me helped (so did a prescription lens, but that's another story).
Benny is absolutely right that adding weight to the barrel can change the harmonics. Benchrest shooters realised some years ago that adding weight at the muzzle could improve accuracy. However they also found that not every barrel needs the same weight to be "tuned".
Weight is also an issue for balancing the rifle. I have 6in and 8in tubes; with the 6in tube fitted the rifle balances well. The 8in tube maes it feel nose heavy. I tried a 12in for a while - the sight picture was great, but my hold deteriorated quickly. That said I know many other shooters who use the same brand of 12in tube with excellent effects.
On a practical note, tubes need to be kept clean. I use a shotgun rod and j-cloth, others a 12/10bore boresnake. You also need to clean the muzzle after shooting. With the tube in place you get much more fouling accumulating on the crown. Your barrle won't shoot better with a dirty crown.
