Cyrille,

I would suggest a money savings here. Not a bank wad full but with 700
board feet of expensive wood I would go with a spline and grove. The
spline could be done with a much cheaper wood and you will get the same
results without wasting 3/4" to 1/2" of material for each joint. Just
make sure you use a wood with the same expansion/contraction
compatability.
