The decision is strictly up to you. As mentioned before about bamboo rods ,I would guess your used to casting a graphite rod and bamboo has a different action & cast differently.

As for your old rod , chances are it's fixable, but you will have to decide weather of not you want to put the time and money into it that may be needed. When you say the tip is warped, I'm assuming you mean has taken a set in one direction or the other and not that the flats of the blank have twisted in a spiral?

A set can be removed in a number of different ways using heat. Guides can be replaced and re-wrapped, grips and reel seats can be replaced. All this requires time and some sort of monitary investment. If your rod was brought back to new or near new condition , its worth would be strictly a measure of love , as it really has no collector value as is the case with most mass produced rods...... Again .....its all up to you.
