Do you not feel the watch when your wrists are hinged during your swing?

Nah. The watch is high enough on my arm to comfortably wear a glove and swing.

I've always worn a watch when I play so it was nothing new for me.

I use both everytime I play

Not at all. I really don't notice it is on. It is super light and slim

I use a laser on virtually every shot. I do use the Golfshot app on occasion, but mostly for hole layouts on courses I'm unfamiliar with. I'll also check it for a layup shot where a quick glance will work and getting the exact distance isn't important or there is nothing to shoot with the laser (end of a fairway, distance to a bunker or hazard, etc).

If I had to choose just one, I'd use a laser every time.

I know this isn't the answer to either question, but i downloaded the Hole19 app (Iphone only) and used it yesterday. Has a great interface, aerial view, movable yardage to/from your location, and green F/M/B distances. I realized halfway through the round that if your scoring club is a 140 club, at the beginning of each hole, it will show you the distance to get to that number. I liked it. I also have a Bushnell V2 but this was nice to show the two other guys playing with me the hole layout on blind shots

I would say it depends on where you play. I have a rangefinder and I like it, but my club puts out pin sheets, so knowing the distance to the middle would be just as helpful to me.

My playing partner and I both used Sky Caddie SGXs for several years. I still do - don't mind the annual fee and I don't want my phone tied up on the course. Last year, he switched to a laser. Now, he routinely asks me for distances to/carry hazards and traps with no line of sight. The laser's contribution is essentially to validate the pin sheet.

I have a Golf Buddy VS4 (GPS) and it's great. Relatively cheap and small. Clips on my belt and provides basic yardage info at the touch of a button. Also has voice so I don't even need to look at it. As I walk up to my ball, just hit the button without looking at it, then select my club and go. Seems to be accurate within a few yards, which is good enough for me.
