On most of my bait reels, I've gone to 20-lb Sufix 832 (0.24 mm dia), and it behaves quite well.
The one spot and one reel I didn't like with braid was my Lew's Custom Inshore, which I had 12-lb fluoro, paired with my ML rod for 1/8-oz lure niche.
Going inside, the Custom Inshore seems to be the least-stout of all my Lew's reels, and when I tried loading a top layer of working braid, you could see a shallow cone line result across the spool width.
If you want reliable casting with light lures and especially light braid, you really need a shallow spool to keep the mass and intertia of the spool + line low. I still haven't gone DD's route of Shimano (excepting spinning reels), am still fond of all my other Lew's reels, and the new shallow spool Lew's Team Pro SP got my attention. The SP also has Lew's centrifugal brake, which is the best casting brake to prevent initial spool overshoot with light lures.

I further reduced inertia in the already light spool with Air BFS bearings. These are small unshielded stainless bearings in barstock spacers.
Also, these were on sale at Japan Tackle, half-price, $14 for the matched Lew's set (so I bought two, a pair for this reel and my Tournament Pro).

The S2 pinion gear in both the SP and Tournament Pro can get away with these light spool bearings, because the drive-side bearing is not involved with the spool, but seats the pinion gear, and the heavy shielded bearing is stout here.

To swap spool bearings, you have to remove (and reinstall) the spindle pin, and the only pin tool that works for this recessed main spool bearing is Daiwa SLP.
This is also a tapered pin, and only goes in and out in one direction - helps to examine this with a magnifier.

The palm-cap bearing is an easy swap, but do it in a shoe box to make sure you catch the bearing retaining spring.

I'm sure you could fish this reel just fine without going to my trouble, but I had a target to use the lightest possible braid - and I love the tinkering.
I also don't like the 8.3 gears, so I slowed them down a bit by swapping to my favorite longer Avail handle.
My Japan order included the bearings, pin tool, handle, and also the braid.
For this (and a few other reels), I'm trying the latest Japan YGK X-braid. In PE# ("Gou"), which I also learned is traditional silk thread diameter measure, this line is PE 1 (0.17 mm = 0.006" dia), and a whopping 22 lb test. The same diameter in Sufix is 10-lb test. The shallow spool holds 200 yds of it.
