Missed this detail. As others have indicated, this is a dual injected engine designed specifically to minimize carbon build-up on the valves. The service they're recommending is unnecessary on these engines. Certainly doesn't hurt to use a fuel "cleaning" additive once every 15k-30k miles, but...
Should be done on direct injected engines. Not sure if yours is. Depends on the year. I’d ask details about how they do it. Hopefully not just a fuel additive. It should be run through the throttle body to take carbon off the valves.
I took a lesson at a local fly shop many years ago. Little tricks from an experienced instructor cut the learning curve dramatically. I passed those tips on to my boys and they both cast better than I do at 6yo and 10yo.
I'd echo most of the brands mentioned and I prefer to start newbies with 5 weight and slow to medium action. I'm a two piece fan, but i get it that four pieces are easier to transport. I'd also suggest 8'6" at a minimum (9ft is my preference).
@millerkiller77's suggestion about a viton o-ring is a great idea. Beyond that, a dry silicone or graphite lube is probably best. Next time it's needed, I'm going to try a PTFE lube (that I use on my bike chains)...
74yd broadhead cold shot yesterday. 2.75” high and right. Jumped in my truck and headed west 10 minutes later. A few more hours to drive this morning, and I’ll be hunting.
