Math & Science ⇒ Ugly Square Root Symbol

[Cham]

I'm having some difficulties with a square-root of a square-root. The results from the code below are ugly, whatever what I try. Do you have a suggestion to improve the output ?

Code: Select all

\documentclass[12pt,letterpaper]{article}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage{amsmath}
\usepackage{tensor}
\newcommand{\qvec}[1]{\boldsymbol{#1}}

\begin{document}
	\begin{align}
		\tensor{\lambda}{_1} &= \sqrt{\sqrt{ \mathcal{I}^2 + \mathcal{J}^2} + \mathcal{I}},
		& \tensor{\lambda}{_2} &= \sqrt{\sqrt{ \mathcal{I}_{\qvec{F}}^2 + \mathcal{J}_{\qvec{F}}^2} - \tensor{\mathcal{I}}{_{\qvec{F}}}}.
	\end{align}
\end{document}

Here's a preview of the results from the code above :

I don't like both outputs. I think the radicals are a bit too big, and the radical's shape isn't the same. I tried the \smash command in several ways but the ouptput it gives is total crap !

As this is a matter of personal test, I don't think that there is really an answer.

Well, how would you do it ?

If you would like to have different roots, you could change the font. For example, here are kpfonts and fouriernc compared - you can see differences:
