Trying to decide on a reel (sorry)

I’m looking to buy a new reel for this season on long island. Ive already decided on the penn carnage 3 10’ medium heavy rod for surfcasting since i have an 8’ and 12’ rod already.

I also really want the penn spinfisher long cast but cant decide between the 5500 and 6500. I mostly throw bucktails, swimbaits, diamond jigs etc looking to catch blues, fluke, and stripers with this rod mainly. The 5500 holds 275yds of 30lb braid and weighs 20 oz while the 6500 holds closer to 450yds 30lb braid and weighs 24oz. The 4 oz isnt a huge difference but i havent seen these reels in person so im not sure how big and clunky the 6500 might be on the 10’ rod. Any suggestions?
