I change 3 guides closes to the handle on 3 baitcasting rod few years ago, and they are still intact today, just for spinning reel application. since I was able to buy stiff baitcasting rod price at a good deal either new or used ones for under $20 , some were 8' ,9' and 7 footer., That was when inexpensive stiff action spinning rod were not too popular 10-15 years ago. Spinning rods were used to be more flexible. Nowadays with IM9, and made in china, price of stiff spinning or baitcasting rod can be bought for $25-$40.
I always admire the stiff action of bait casting rod, just not always impress with the price.
I also salvage the guides from broken rods or pick them up on fishing ground whenever I saw broken rod section.
In terms of birdnesting, there are few videos on how to untangle them in no time. After I saw those videos, and how easy to untangle birdnest, that was when I bought my first baitcasting reel.
Practice with 15 lb mono, easier to untangle them. then put 30 lb braided as minimum size, or leave the 15 lb mono there. When fishing heavy weedy carpet type area, such as fishing at rice lake, I would be using 50 lb braid, easier to untangle them on birdnest., and more power to haul fish out of cover. The size of lure should also be at least 1/2 oz or more. lighter size lure casted on windy day have more potential of causing birdnest.
