I'm sure you'll love it. A buddy of mine bought a trap right after I bought my H-web and he loves it as well. I'm considering getting another 12.5"-13" to use as a spare, bad weather, all that stuff.
Check the classic fielding glove at Boombah, they're $30. I have a 13 inch h-web, it plays a little smaller than 13" but would be great if you play mostly infield and some outfield. I would recommend trails over turfs if you also play outfield, but regular turfs can be had for about 1/2 the...
Idk about the Swarm's but the Hellcat's are definitely not as narrow as the Speedcross 3's. Those things are so damn tight and I do not have large or wide feet by any standards.
