2x9 is way too big for you. Vacu-tech is notorious for inaccurate measurements. Always get a size smaller than what they recommend or you'll be stuck with a tube that sucks your scrotum in and make it very very difficult and painful.
Also, I highly recommend getting a thickwall cylinder over flared every time. You will like it much more.
I recommend:
Penis Enlargement Vacuum Cylinders by Thickwall Cylinders - Vacuum Pumps for cock and balls enlargement, rosebuds and nipples.
as they are cheaper than Vacu-tech, but the same exact quality. I know because I've used Vacu-tech products for many many years and, of course, ordered what they recommended and it was too big.
Don't be cheap and get the MightyVac or whatever it's called. You pay for the cheap quality and you'll be disappointed. For the thickwall cylinder alone, you'll looking at about 80.00. Get a pump with an air release trigger and gauge so you can monitor the pressure. So, expect to pay about 130-140 for a real good solid kit that's well made and will last.
Here's how you measure accurately so you don't fuck yourself over by measuring wrong. Take a sheet of paper and wrap it around the midsection of your shaft while you're squeezing it (should be the widest part), mark it, unfold the paper and measure the length. If you're a solid 5.25"-5.5" girth, order a 1.5" by 9 thickwall and you'll be allllllll set for a long time. If you're between 5.5"-6.0", a 1.75" by 9 thickwall will be a great fit. It took me a few trials and wasted money to get the right size so this is solid advice.
One more thing, if you're cut, that'll be most ideal for pumping. If you're uncut, you're going to get what they call the donut effect which is when lymph build up gets trapped at the foreskin area...not too pleasant. But that's also because of excessive pumping, aka you've pumped too long during one session so just ease off and let the fluid disperse over a few hours. I know all this because I was uncut up until age 27, now 29. Pumping while being cut is much better and the effects look better (no donut effect).
I'm about 5.4"-5.6" girth (depending on how hard the squeeze/erection is) and I'm very comfortable with a 1.5" by 8". I didn't get the 9" because I figured 8" is enough and I wouldn't reach the top, but I'm slowly reaching the top so I'll have to get another one...maybe.
Hope that helps you decide.
Update:
So I went and check it out for you the starter kits:
http://www.thickwall.co.uk/starterkits.htm
After conversion, it's about 111 USD which is a solid deal. I think I spent close to 200 alone on the wrong tubes, either wrong in size or wrong in style. Argh.
These starter kits have the trigger pumps I'm using and looks to be the same as Vacu-tech, but much cheaper. Anyway, enough of me...good luck!
