For a line counter, the Sealine SG47LC is a good bet. I'd opt for the 47 rather than the 27 for more capacity, low gear ratio and tougher drag. The 27 will be fine if you're strictly fishing Erie for wally's and bows but you'll benefit from the 47 when using dipsy's, inlines or Lake O Salmon hunting.
You also mentioned leadcore... you'll want a dedicated setup for this. A roller tip or all roller rod is nice but at the very least you'll want something with a big eye on the end. As for reels, you can't get much better value than a Penn 209M for 18lb leadcore or a 309M for 27lb leadcore. You don't need a linecouter, just count your colours.
