Not sure how many hand tool users there are here but I’m going to buy a new plane and am debating between a plow plane or a combination plane (both Veritas). Plow plane gets me what I need today which is cutting grooves, dadoes, etc but the combination obviously gets a bit more in functionality and available blade shapes plus it has nickers on both sides so reversible direction. I already have a router plane with a fence which is almost as good as a plow but not quite. Trying to figure out if combination plane has any down sides to it at all that I’m not thinking about before I pull the trigger on it.
I’ve honestly never had a problem with grain direction, but I’ve also had pretty good luck being able to select good boards to avoid wonky grain when I need to use the plow. Having both handed versions would certainly be a luxury, but I definitely don’t think it is necessary, personally
