Reddit mentions: The best tennis court equipment

The only thing I could suggest is to talk to a Deva cut stylist about keeping the length, but cutting some layers in, perhaps? Also, experiment on your hair during your days off: try a lightweight leave-in conditioner, air dry your hair in a heavy duty hair net, called a triangle net (like this one:https://www.amazon.com/Diane-Cotton-Triangle-Net-Black/dp/B003SYVKCC/ref=sr_1_8_a_it?ie=UTF8&qid=1481562681&sr=8-8&keywords=Hair+net#customerReviews) You might be able to find one at your local Sally Beauty Supply. Also, experimenting with washing you hair at night, and sleeping on a satin pillowcase is an option too. Good luck!

I'm assuming ballport = ball hopper/ ball bucket?

This is the ball hopper I have: http://www.amazon.com/gp/product/B000MKQ23W/ref=pd_lpo_sbs_dp_ss_3?pf_rd_p=1535523722&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0019F03MK&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0S45BQRV0SH9NWD8H488

Very durable since it's metal and it make is easy to pick up balls.

In terms of practice, it's great for doing serve practice or drills off of ball feeds.

Overall I tend to practice more without the ball hopper as I tend to hit around or play games with my hitting partner.

But the times when you want to get a lot of repetitions within a short time frame, the ball hopper is invaluable.

As far as balls. I just tend to use Penn Championship extra duty. I can pick up a box of 20 cans from Costco really cheap. I usually open half and put it into the hopper then just add balls from practice sessions and matches.

I have low-porosity hair that's fine and thin, so while I don't get the heavy head, I do get the long dry time.

You could try switching your plop material partway through? I plop with a t-shirt for the first half hour, then swap to a cotton net like they use for curlers. Here is what I bought. I ended up with a box of 12, I don't know if that's intentional or a misship by the seller, but I'll accept it. Hell, if you're interested, I'll send you one, I still have the 11 extras, LOL.

Oh I like that it does that, but if I don't want it to do that I got this net that keeps the clumps intact:

If you want to live large though, you go with the Ballmower.

Im already designing a version of this for Peachtree District:

Have you tried these Tourna Tenn-Tubes?

It is a tennis ball hopper/collector

These don't roll around, but they've been around forever, are (probably) cheaper, and stand up on their own: https://www.amazon.com/Wilson-Tennis-Ball-Pick-Hopper/dp/B00F16NQCM

From a practical standpoint, I prefer a standard wire ball hopper (Example). Sure it doesn't roll, but the same concept applies where you plop the hopper onto the balls to get them inside. But it also lets you grab balls for practice, where this roller would probably need to be emptied somewhere.
