Yeah - if you read those threads you'll see I'm not a fan of having the rod tips sticking out like that - you're just asking for broken rods.
Although I have a Pack and not a Guide 119 I have some tips for you to try out.
#1 How about paddling it around stock first, then start modifying it? You may be trying to fix some things that aren't broken.
#2 An anchor "system" is about the last thing I worry about when fishing our Ozark rivers. The places where an anchor would be really helpful to fish are usually places you shouldn't anchor anyway, and I have learned the key to really catching fish is the mobility you have - not sitting in one spot like I'm baitfishing.
#3 The more "stuff" you clamp, glue, or screw to your boat the harder you make it to paddle or portage. Simple (and easily removable) is usually better.
#4 A kayak paddle is great for making fast time, but sucks for maneuvering while fishing. A single paddle is tops for that, but carrying both is a pain. I rarely use the double-blade, even when paddling upstream, but I do have arms like Thor. You'll find what works for you.
Congratulations on the new boat, I'll probably pick one up at that price - how can you beat it?
