I'm by no means an "expert" on this subject...but I do have some experience (11 years & counting with this building addiction) also I'm in construction (tile contractor) so iv'e tried many different types of wood (picking up scraps left by carpenters & cabinet makers) redwood,pine, cedar, alder, oak, basswood, poplar and last two years switched over to AZEK PVC (no issues with water intrusion)...that having been said iv'e enjoyed working with basswood, great for top water especially stick baits & lunker style baits....it can be purchased on Ebay, michaels or other craft stores...for snack size baits 4-6 inches & gliders/jointed swimmers to about 8 inches poplar was my wood of choice for several years ...it can be purchased at the Big Box lumber stores ....actually you can get dowels in varying diameters in poplar that work great for slammer / rat baits...although Iv'e been at it for some time i have limited tools...i have scroll saw & small band saw for cut-outs, a one inch belt sander & palm sander for shaping /sanding (as well as a sheet rock knife ) as a consequence most of my baits would be referred to as Flat Sides although i try to compensate for depth with added features i.e. jaw bone, gill plates fins tails etc...as you begin your journey into this addiction take it slow & read all you can (as well as watch videos on youtube ) it's all out there..First & foremost Enjoy yourself realize we've all experienced the "learning curve" required to satisfy ourselves...michel
